MIOHAEL OONNER, OF PLYMOUTH, MICHIGAN.

Letters Patent N0. 108,762, dated November 1, 1870.

IMPROVEMENT IN TINS MITHS FURNACESL The Schedule referred to in these Letters Patent and making of the same.

To whom it may concern Bait known that :I, meant c mm, of Plymouth, in the county of \Vaync and State of Michigan, have invented a new and useful Improvement and it consists in the arrangement of its several parts,

whereby greater economy in the consumption of fuel is attained, as more fully hereinafter set forth.

In the drawiug+ A represents an ormnary sheet metal cylinder, provided with a cover, B, and hearth, O, in front of the opening through which the ironsare inserted; D is an ash-drawer under the grateall of which are of the usual construction.

E is a rotary or mill-grate, in two sections, each provided with a series of radial openings; the lower section is secured to the walls of the cylinder above the ash-drawer, while the upper is pivoted to the lower, on which it receives an alternating rotary motion from a hand-lever projecting through the wall of the cylinder under the hearth.

F is the flue, which issues from the rear wall of the cylinder, opposite'thc hearth and on a plane therewith; in the fine is the usual damper,'I to check the combustion of. the fuel when necessary. o

By taking the flue out at this point, a horizontal drait is secured, which causes the lower strata only -of the fuel to ignite, and at the point where heat is required, thereby saving a considerableamount thereof, as compared with furnaces of the ordinary consideration, in which the exit of the smoke and gases of COll'lbllS? tion being at or near the top, the entire fuel contained in the cylinder is ignited. In this furnace, when the stratumv of fuel on thel'grate and about the irons is consumed, the ashes are shaken into the ash-drawer by vibrating the grate, which brings down a fresh sup ply of fuel, caused by the settling of the mass above.

What I claim as my invention, and desire to secure by Letters Patent, is- I c In 'a tinsmith furnace, the grate E and fiuel? constructed and arranged with relation to the. cylinder A, cover B,and hearth G, as described and shown, and as and for the purposes set forth.
